RONGLALITE

RONGALITE Rongalite lump, Rongalite powder are of a sort but in different forms, their chemical composition is all the same. Three types of Rongalite product are supplied to meet customer’s demand in application. Propeties: Chemical name: Sodium Formaldehyde Sulfoxylate Commercial name: Rongalite Molecular formula:NaHSO2CH2O2H2O Mloleculare Weight: 154.12 Specific Gravity: 1.8 Melting Point: 64℃ Heat of Fusion: 54.84KJ/MOL(13.2KCAL/MOL) Hygroscopic point: Relative Humidity 60% Stable pour-point: 50℃max Solubility: 45%(20℃):1.2 dose of water is necessary for dissolving away 1 dose of Rongalite at 20℃ 50%(70℃):1 dose of water is necessary for dissolving away 1 dose of Rongalite at 70℃. Physical Properties: To be nominated for rongalite is for the reason that it serves the color-discharging function to fabrics as well as its appearance. Under different cooling conditions, it solidifies out into white lumps or powder. Standard: Content of NaHSO2CH2O   98%min.
